Exploring General Algebraic Relationships Spreadsheets
Use a spreadsheet to verify that
2a + 2b has the same value as 2(a + b)
In Excel input formulae in C1 (=2A1+2B1) and in D1 (=2(A1+B1)
Input different values for A and B in A1 and B1
Verify that C1 and D1 will always show the same number
Graphical Calculator
Using a graphical calculator:
Work through calculator operations by following step-by-step instructions and illustrations, then practice your skills with similar exercises.
These are the calculator operations you will encounter most frequently in your study of mathematics.
The step-by-step instructions walk you through the operation guiding your way along each and every keystroke.

Verify that
(x + 4) – (x – 1) = 5
Input
Y1 = x + 4
Y2 = x – 1
Y3 = (x + 4) – (x – 1)
Use the table to confirm that 4 – (-1) = 5
Draw the graph of the two straight lines for Y1 and Y2
Confirm that they are parallel lines with a vertical distance between them of 5
